Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, serve as a comprehensive framework for the regulation of civil aviation within the country, ensuring the safety and efficiency of air travel. The regulations are designed to fill gaps in aviation safety and operational standards, providing clear guidelines and requirements for aircraft operation, maintenance, and airworthiness. The inclusion of Part 39, which focuses on specific airworthiness directives, illustrates the commitment to addressing particular safety concerns and ensuring that aircraft meet stringent safety criteria. One such directive is AD/PA-23/62, which pertains to Piper PA-23 (Apache and Aztec) series aeroplanes fitted with Airesearch turbochargers. This directive mandates the provision of drainage holes in the engine lower air scoops and fairings, as specified in Piper Service Letter No. 705, to be completed within 100 hours of time in service after 31 July 1974. The policy objective is to enhance the safety of these aircraft by preventing potential fluid accumulation issues that could compromise engine performance and safety.

Scope and Application

The Civil Aviation Regulations 1998, as amended, pertain to the regulation and safety of civil aviation within Australia and its territories, establishing comprehensive standards that govern all aspects of airworthiness, licensing, operations, and maintenance. Specifically, Part 39 - 105 of these regulations outlines the Civil Aviation Safety Authority's schedule of airworthiness directives, which include mandatory safety instructions and modifications to be implemented for certain aircraft types to ensure ongoing airworthiness. For instance, AD/PA-23/62 pertains to Piper PA-23 (Apache and Aztec) series aeroplanes equipped with Airesearch turbochargers. This directive requires the installation of drainage holes in the engine lower air scoops and fairings to comply with Piper Service Letter No. 705, within 100 hours of time in service after 31 July 1974. This regulation applies to all PA-23 series aircraft meeting the specified criteria, ensuring that they maintain the required safety standards. The directive's scope is limited to the specified aircraft and does not extend to other types unless similarly identified in other airworthiness directives.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, detail the requirements for airworthiness directives concerning certain aircraft models, with AD/PA-23/62 focusing on Piper PA-23 (Apache and Aztec) series aeroplanes. This directive applies to all PA-23 series aeroplanes equipped with Airesearch turbochargers (Section 1). The primary requirement of this directive, as outlined in Section 2, is the installation of drainage holes in the engine lower air scoops and fairings. This must be executed in accordance with Piper Service Letter No. 705. The compliance period for these modifications is within 100 hours of time in service after 31 July 1974 (Section 3). The obligations imposed by these regulations are clear and precise. Operators of the affected aircraft must ensure that the specified modifications are completed within the stipulated timeframe to maintain the airworthiness of their aeroplanes. The installation of drainage holes is essential to prevent fluid accumulation that could otherwise compromise engine performance and safety. This requirement is not merely a suggestion but a mandatory directive that must be strictly adhered to by all relevant parties (Section 4). Failure to comply with these airworthiness directives can result in significant consequences. According to the regulations, non-compliance may lead to various civil and criminal penalties. Specifically, operators who do not adhere to the directive within the specified timeframe could face enforcement actions by the Civil Aviation Safety Authority (CASA). These actions could include fines, suspension or revocation of the aircraft's operating certificate, or other regulatory measures deemed necessary to ensure compliance with safety standards. The exact penalties can vary based on the severity and frequency of the non-compliance, but they underscore the importance of adhering to the directives to maintain the safety and legality of aircraft operations (Section 5).
